Work on this experimental vehicle started in March 1943. Two prototypes were built by July. The vehicle passed trials, but was never mass-produced or used in action.

The tank was intended to use parts and components of the Pz.Kpfw. III and Pz.Kpfw. IV vehicles. Existed only in blueprints.

This experimental version of the Pz.Kpfw. IV Ausf. G, incorporating hydrostatic drive, began development in 1944. Trials were discontinued due to the unreliability of the transmission and the lack of spare parts.
